In 2009, the International Air Transport Association (IATA), the global trade association for cargo and passenger air carriers, set three goals for the reduction of carbon dioxide (CO2) emissions...Airlines are expected to achieve their goal of an average improvement in fuel efficiency of 1.5% per year.

In our recent transatlantic airline fuel efficiency study update, we compared the fuel efficiency of 20 airlines with routes between the United States and Europe. Most of the transatlantic routes in...Finding the lowest carbon flight for a specific trip is more complicated than simply choosing the most fuel-efficient carrier.

There’s an old saw, most famously attributed to Benjamin Franklin, that nothing in life is certain but death and taxes. More recently, some have argued that the return of commercial supersonic flight...Despite a nod to supersonic aircraft in the new FAA reauthorization, CO2 and noise standards are still uncertain.

In 2016, Sir Richard Branson, president of Virgin Atlantic Airways, announced that the Virgin Group would assist aviation start-up Boom in developing a new supersonic transport (SST) aircraft. Boom...Boom Technologies' CEO claims the company's proposed supersonic aircraft's fuel burn will be on par with subsonic business-class travel. Will it?

The International Civil Aviation Organization (ICAO) has not yet figured out how to decarbonize jet fuels. Under the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA),...ICAO's Carbon Offsetting and Reduction Scheme for International Aviation will probably not provide a meaningful framework to transition to alternative jet fuels.

This paper provides a preliminary assessment of the environmental performance of new commercial supersonic transport aircraft (SST). Three U.S.-based startup companies are working to develop new SSTs...

Following in the footsteps of the 2010–2014 airline rankings, this study ranks U.S. domestic air carriers by their overall fuel efficiency for the years 2015 and 2016. The analysis continues the use...

Many of us in the aviation field are in serious need of an airsickness bag, given the turbulence we’ve experienced recently over the Bombardier CSeries. That’s the new aircraft developed by the...Bombardier's new aircraft is mired in trade disputes, and that's creating some uncertainty over Delta Air Lines' order for 75 CS100 planes. But if Delta keeps its eye on the fuel savings it will reap...

It’s been a dizzying couple of weeks for those (admittedly few) of us who work on aircraft emissions. Two weeks ago last Friday, the Center for Biological Diversity announced that it had sent the U.S...Next year, EPA has the chance to propose an ambitious GHG standard for aircraft to promote low carbon aviation. It alluded to the possibility of going further than the UN’s weak recommendations in...

Part 2 in a series featuring interviews with members of the technical advisory group who worked with the ICCT on our cost assessment of near- and mid-term technologies to improve new aircraft fuel...Why real-world aircraft fuel efficiency improvements fell short of ICAO's mid- and long-term fuel burn technology goals for aircraft designs and what can be done to get us closer to achieving them....
